Última New insight into how thigmomorphogenesis affects Epipremnum aureum plant development Horticultura Brasileira Benedetto,Adalberto Di; Galmarini,Claudio; Tognetti,Jorge. ABSTRACT Climbing Epipremnum aureum plants develop larger leaves than unsupported, hanging plants. This effect may be regarded, in part, as a thigmomorphogenic response, but gravimorphogenetic effect may also be involved, since polar auxin transport is known to be negatively affected in plants with horizontal or hanging stems, which may result in an altered hormone balance at the whole plant level. The present work was aimed at studying how exogenous auxins and cytokinins may influence growth of E. aureum rooted cuttings under different training systems. Rooted cuttings of E. aureum were cultivated either climbing on an upright wooden board or creeping on the glasshouse bench or hanging from a basket. All leaves of each plant were sprayed to run-off at... Tipo: Info:eu-repo/semantics/article Palavras-chave: Auxin; Citokinin; Foliage plants; Gravitropism; Leaf growth; Leaf anatomy; Photosynthesis.

URBINA,DANIELA C; SILVA,HERMAN; MEISEL,LEE A. Thapsigargin, a specific inhibitor of most animal intracellular SERCA-type Ca2+ pumps present in the sarcoplasmic/endoplasmic reticulum, was originally isolated from the roots of the Mediterranean plant Thapsia gargancia L. Here, we demonstrate that this root-derived compound is capable of altering root gravitropism in Arabidopsis thaliana. Thapsigargin concentrations as low as 0.1 µM alter root gravitropism whereas under similar conditions cyclopiazonic acid does not. Furthermore, a fluorescently conjugated thapsigargin (BODIPY FL thapsigargin) suggests that target sites for thapsigargin are located in intracellular organelles in the root distal elongation zone and the root cap, regions known to regulate root gravitropism Tipo: Journal article Palavras-chave: Arabidopsis thaliana; Ca2+-ATPases; Calcium; Gravitropism; Thapsigargin; Root.
